THE ORCHID REVIEW. 279 
stage suitable for that operation, and afterwards bear in mind the advice 
proffered in last month’s Calendar respecting over-watering. In addition to 
O crispum, such species as Hallii, triumphans, tripudians, and those of the 
luteopurpureum section, with the natural hybrids elegans, excellens, &c., 
will all need attention this month or next. Also O. cordatum and 
maculatum, Oncidium olivaceum (cucullatum), Phalznopsis, and nubigenum 
are commencing to grow, and should, so soon as they have made sufficient 
progress to suggest the early appearance of roots, be given fresh rooting 
material, and shortly afterwards a more liberal supply of water. 
The Pleiones have now about completed their growth for this season, 
and the leaves which are deciduous will soon fall away. Bearing this in 
mind, much less water should be given, though until the flowers appear the 
compost should not become dust dry. There is with these practically no 
resting period, for almost before the old leaves have disappeared the young 
growths, in which the flower scapes come up, make their appearance, hence 
growth in some shape or form is always in progress. P. humilis is only 
about half-way through its season’s work, and must still be given a fair 
average supply of water. 
Thunias, Bletia hyacinthina, and any other Orchid that has been 
standing outside during the summer, must now be brought in and placed in 
a dry, cool position in which to pass the winter. If the leaves have not 
all fallen off the Thunias, water should be still supplied, though not: often. 
The evergreen Disas that have been in a frame had better be removed 
to a place where frost is unlikely todo them harm. A position corresponding 
to the one occupied by them outside should be selected, so that the growth 
made will not become attenuated and weak from excessive heat and moisture ; 
the latter, of course, is appreciated, but an abundance of air at the same 
time is as essential to their well-being. We re-pot our plants in the spring, 
but now is also a suitable time for those that were not done early in the 
year. Well drained pots or pans should be used, and a compost consisting 
of sandy peat two-thirds, and the remaining third of chopped moss and 
coarse silver sand, mixing in as the work proceeds a few lumps of sandstone. 
The young plants should be potted together according to their size and 
strength, so that they will under ordinary circumstances flower all together. 
The smaller runners may be put in a pan to grow on fora season. A good 
soaking should be given when completed to settle the compost about their 
roots, afterwards a moderate supply will suffice so long as the soil does not 
become dry. Of the deciduous Disas I have nothing to szy, as my ex- 
perience with them is not of a suitable nature to place on record. 
The Barkerias, thanks to the brilliant weather experienced this year, 
have made excellent headway, and are now throwing up their slender 
flowering stems from the apex of the growth, and new roots are pushing out
